About CATO
CATO Research Chemicals Inc. supplies reference standards, impurities and labelled analogues to pharmaceutical companies, contract laboratories, research institutes and testing organisations — with the analytical documentation that regulated work requires.
What we make
- Impurity standards — pharmacopoeial and non-pharmacopoeial impurities, degradants and process-related impurities of active pharmaceutical ingredients.
- Metabolites and toxins — including mycotoxins, marine biotoxins and their labelled analogues.
- Stable isotope-labelled standards — deuterated and 13C-labelled internal standards, including labelled nitrosamines.
- Reference materials for food and environmental analysis, and quality-control samples.
What we do beyond the catalogue
- Custom synthesis of compounds that are not commercially available.
- Isolation and purification from related materials, and preparative separation.
- Structural identification of unknown impurities from spectra supplied by the customer.
How we work with laboratories
Enquiries are handled by a technical contact who can read a structure and a method: send the CAS number or the impurity designation, the pack size, the quantity and the date you need it, and the reply will cover availability, documentation and shipping in one message.
Quality
Every lot is certified individually, and the certificate states the analytical basis for the value assigned to the material. The company holds ISO 17034, ISO 9001, CNAS, SGS certification; scope statements are available on request. See Quality and documentation for detail.
